Developing a computational model for human neural tube closure

03:052 years ago

Animal-free methods for human chemical safety assessment are promising tools for the reduction of animal testing. However, these methods only measure a small aspect of biology compared to an in vivo test. The reductionist nature of these methods thus limits their individual application in the regulatory arena of chemical risk assessment. Ontologies can be used to describe human biology, and delineate the basis of adverse outcome pathway networks that describe how chemical exposures may lead to adverse health effects. This pathway description can then help to select animal-free in vitro and in silico methods, comprehensively covering the network. The comprehensiveness of this approach, firmly rooted in human biology, is expected to facilitate regulatory acceptance of animal-free methods. As an example, this video zooms in on the development of a computational model for neural tube development, an aspect of human development that is especially vulnerable to chemical disruption.

This research is part of the ONTOX project.

User Research in developing the virtual human platform

Digital tools can support the phasing out of animal-based tests and data in chemical risk assessment. This is one of the core promises of the Virtual Human Platform. The potential contribution of digitalization is linked to the acceptance and adoption of tools, methods, and data by stakeholders in several societal sectors. To facilitate the integration of stakeholders in the configuration of digital tools, Dr. Isaac Ortega Alvarado and colleagues gather insights from risk assessors in their role as users. Risk assessors are the ones who actualize chemical risk assessment and its standards through their practices. With this perspective, this research contributes to understanding the development and implementation of digital tools as embedded in social processes of construction and reception.

NXTGEN Hightech Biomed

The Netherlands has strong academic knowledge in areas like Lab-on-Chip, Organ-on-Chip, artificial organs, and cell production technology. However, turning this knowledge into actual products is challenging due to the need for collaboration between different technological and biological specialists. The NXTGEN Hightech program (https://nxtgenhightech.nl/en/biomed/) addresses this by creating a collaborative environment where companies from various fields work together. This approach aims to transform academic insights into innovative products, benefiting both the industry and society.
